HENRY O. NEWMAN, OF COLUMBUS, OHIO.

BRICK OR STONE MASONS GAGE.

SPECIFICATION forming part of Letters Patent No. 718,789, dated November18, 1902.

Application filed March 31, 1902. Serial No.100,'82. (No model.)

fo all whom it may concern:

Be it known that I, HENRY C. NEWMAN, a citizen of the United States,residing at Oolumbus, in the county of Franklin and State of Ohio, haveinvented certain new and useful Improvements in Brick or Stone MasonsGages; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same. l

The invention relating to brick or stone masons gages has for its objectto provide devices whereby the work of locating Vertical and horizontallines to serve as guides for laying courses of brick or the likeinerecting buildings is facilitated. Devices have heretofore been proposedfor this purpose; but so far as I am informed they were of expensive andcumbersome construction and troublesome to manipulate. The aim of myinvention therefore is to provide a simplified and easily-manipulatedconstruction capable of reliably performing the functions for which itis designed.

In the accompanying drawings, forming a part hereof, Figure l is a sideelevation of the principal apparatus, the vertical gage being broken outor shortened to permit illustration in connection therewith of theplumbing device. Fig. 2 is a plan view. Fig. 3 is a similar view of thedevice for holding the free end of the horizontal or twine gage. Fig. 4is a view of the plumbing device viewed from a plane at right angle tothat from which that device is seen in Fig. l. Fig. 5 is a plan view ofthe adjustable twine-gage holder employed in 'connection with thevertical gage-rod in locating the line for exterior angles. Fig. 6 is afront view taken on the plane x, Fig. l. Fig. 7 is a view of the underside of the maii. shoe, showing an attachment thereto whenA theapparatus is used at interior angles. Fig. 8 is a central sectional viewof the attachment referred to in the description of Fig. 7. Fig. 9 is aside View of the twineholder that is applied to the vertical gagerodwhen the apparatus is used in interior angles. Fig. lO is a plan view ofthe attachment referred to in Fig. 9.y

Like characters of reference in the several views designatecorresponding parts.

l designates the main or primary shoe, adapted to have one portionplaced in the mortar-space between the bricks at the corner of the work.2 is a bracket on the upper side thereof, having a vertical arm 2a and ahorizontal arm 2b, the said bracket being pivoted in ears la on theprojecting part of the shoe 1. Passing loosely through the horizontalarm 2b and engaging the shoe l or a suitable plate thereon is ashouldered thumb-screw 3, and around the screw is a spring 3, tending tolift the arm 2b, so that by turning the screw in the proper directionthe vertical arm 2l can be adj usted on its pivot toward or from thevertical. a bracketed arm 4. To assist in holding the arm 4 against thearm 2a, I can employ a headed screw 4d, passing through an arc slot 2din the arm 2a. (See Fig. 6.) The arm 4 is pivoted so as to swing in aplane at right angles to the plane in which the arm 2n swings, and`passing loosely through an eye 2e on the arm 2a is a shoulderedthreaded thumb-screw 5, that engages an eye 4b on the arm 4, the screwbeing provided with a spring 5a, tending to separate the eyes, so thatby turning the screw 5 in the proper direction the arm 4 can be swung onits pivot 4a toward or from a vertical plane passing through said pivot.In brackets 4c on the arm 4 is removably placed the vertical gage or rod6, shown to be hollow and having straight edges. This rod has a stop 6ato limit its entrance between the brackets 4c. It is obvious thatPivoted at 4a on the arm 2 is by properly adjusting the screws 3 and 5the rod can at any time be swung into a vertical position. The arm 2bcan be held after adjustment by means of a set-screw 2f engaging saidarm and pinching the shoe. certain the vertical, I provide in theupperend of the rod (which serves as a socket) a plumbing device comprisingthe usual bob 7 and line 7a, the line being attached to the upper end ofa plate 7b, that is marked to indicate a line coinciding with the axisof the rod 6. The bob, its line, and the indicatorplate are incased in aclosure 8, having transparent .walls to protect them from wind, dust,&c. The case is furnished at its base with a stem 8, that its in theupper end of the rod 6, and the case can be turned on its stem at leasta quarter-circle, so that the de- To asl IOO lection of the bob-linefrom the line of the axis of the rod 6 can be seen and the rod adjustedby the screw 3 or 5 accordingly.

In Fig. 5 I have illustrated a twine-holder that is adapted to be placedon the vertical gage-rod 6 when the apparatus is used on the exteriorangle of a structure. This holder comprises two symmetrical arms 9,shaped to embrace diagonal corners of the rod 6 and hinged together atone end, as seen at 9a, and provided with a screw 9b, adapted to drawthe arms 9 together upon the rod 6. The arms 9 have extensions 9,diverging at right angles, (if the corner is to be built on that angle,)said extensions being notched, as seen at 9d, to receive the knottedends of the horizontal twine gage 10. Obviously this cord-holder canbeadjusted up or down on the rod 6 by releasing and retightenng the arms9. The other or free end of the horizontal or twine gage 10 is held in anotched slide-block 11, vertically adjustable by means of aclamping-screw 11a on a vertical rod or standard 12, having fixed at itslower end a shoe 12, similar to the shoe 1, adapted to be held in themortar-space between bricks at any suitable distance from the gage-rod6.

The principal shoe 1 can be provided at its under side with two pins 1b(see Fig. 1 and dotted lines Fig. 2) to t on the corner ot the brick todetermine its position at the corner, and an adjustable set-screw 1c ina bracket 1d at the under side of the shoe can be used to adjust andsteady in the proper position the outer portion of the shoe 1.

When the apparatus is to be used in the construction of interior angles,the end of the screw lc is furnished with a small angular block 13,secured to the end of said screw 1c by means of a small thumb-screw 13a.

In Figs. 9 and 10 I have illustrated a twineholder that is to besubstituted for that shown on the vertical gage-rod 6 in Fig. 1. In this`form an angular projection 9a, constituting an extension of one of theclamping-arms, is

provided, which projection is notched, as seen at 9f, to hold theknotted end of the cord.

What I claim, and desire to secure by Letters Patent, is-

1. In a brick or stone masons gage, the combination with the shoe, of abracket hinged to the upper side thereof and adjustable thereon in oneplane, and an arm hinged to the iirstmentioned bracket adjustable in aplane at an angle to the first-mentioned plane, anda gage-rod for thesaid arm.

2. In a brick or stone masons gage the combination with the shoe, of abracket adjustable on said shoe in one plane, a gage-rod adjustable onsaid bracket in a plane at an angle to the rst-mentioned plane, and aplumbing device for the end of said rod.

3. In abrick or stone masons gage, the combination with the shoe, of abracket hinged to t-he upper side thereof and adjustable in one planethereon, an arm hinged to said bracket and adjustable in a plane at anangle to the first-mentioned plane, a gage-rod supported by said arm,and a twine-gage holder adjustable on said rod.

4. In a brick or stone masons gage the combination with the shoe, of abracket on the upper side of said shoe adjustable in one plane, agage-rod on said bracket adjustable in a plane at an angle to theiirst-mentioned plane, and means on the under side of said shoe forengaging the angle ot' the brickwork, substantially as described.

5. In a brick or stone masons gage the conibination with the shoe of abracket adjustable in one plane on said shoe, an arm adjustable in aplane on said bracket at an angle to the iirst-mentioned plane and agage-rod removably supported in said arm.

In testimony whereof I affix my signature in presence of two witnesses.

HENRY C. NEWMAN.
